One night on a stakeout Agito looks over at Akira, who is half-asleep in spite of all the energy drinks he's been drinking, and realizes suddenly that for the first time since his birth he actively doesn't want to disappear.

When he wakes up in a hospital bed after the battle for the fang regalia and finds his ribs broken and his feet bare, it's only Akito's desperate pleading (please Agito, no, you promised you'd fight for me, please don't leave me alone again) that convinces him not to.
